Doctoral assessment of students is probably the most well-developed of all levels while master's students vary so much that it might generate the most interesting information. Are there capstone courses? Is there a process for identifying problems before students proceed too far into the program.
One thing that concerns me is that the survey needs to distinguish the units of analyses. If you're interested in program assessments, then you should probably include indicators such as student placements, rankings, employee satisfaction, etc. These data, however, are difficult for universities to get. Since all graduate programs in Missouri are accredited by HLC and many also have specialized accreditation, perhaps the team could find a means of gathering quality data from those self-studies.
